🧪 Usage

1️⃣ Standard (Shake + Vibration)

By using the built-in presets — light, medium, heavy and custom — you can quickly apply different vibration intensities and patterns, perfectly paired with UI shake animations for a dynamic and responsive user experience.

final shakeKey = GlobalKey<ShakeWidgetState>();

ShakeWidget(
  key: shakeKey,
  preset: ShakePreset.medium,
  child: Text("Tap Me"),
);

// Somewhere else, e.g., on button press:
shakeKey.currentState?.shake();

---

2️⃣ Shake Only (No Vibration)

If you only want the visual shake effect without vibration, you can set vibrationType to VibrationType.none using the ShakeConfig. To customize the intensity of the shake, adjust the offset value — higher values will produce a stronger visual effect.

ShakeWidget(
  key: shakeKey,
  customConfig: ShakeConfig(
    offset: 20,
    vibrationType: VibrationType.none,
  ),
  child: Icon(Icons.info),
);

---

3️⃣ Advanced Configuration: Full Control Over Visual and Vibration Effects

You can also create custom vibration patterns by setting vibrationType to VibrationType.custom, and providing your own pattern and intensities. This gives you full control over the vibration behavior.

ShakeWidget(
key: shakeKey,
customConfig: ShakeConfig(
offset: 32,
pattern: [0, 50, 100, 50],
intensities: [255, 0, 255, 0],
vibrationType: VibrationType.custom,
),
child: Text("Custom Shake!"),
);

Trigger it via:

shakeKey.currentState?.shake();
